licm'zion filed July 16, 1912'; PP

To all whom may concern.

known that i, W'INGENT d. Bonner, e citizen of the "United States, and resident oi"? Chicego, in the county of Cook and State Illinois, have invented new end useful Iniproveznent in Side Bearings for Cars; and I do herehy declare the foilowing to bee. full, clear, and exec. description thereof.

7 invention relates to side-hearings The object oi? my invention. is to provide side-hearing;- of simple end strong con struction that will provide for free rolling trowel for normsl conditions and e sliding; travel, for ehnormnhx H hotly-plate in ehi'iormsl condition should cause a flat spot, this Wonid not he objectionable with my construction, as it will he cleeriy seen that the rolier will not make a. complete revolution, therefore, e fist spot at this point on the 'cnnifei nee, would not affect the normal of the roller. To ends my inventon comprises the s o. A? J I. 4. a. .1. novel ieeseres hereinafter set .lOLbil and for v the lower hearing block or housing provided "with the guides 3 at each side thereof and progecting nwardly iron). the inner S1l-- Welis 4 f the housing. These guides are provided with the openings 5 for the ad nizssion of the lugs 6 on the roller 7. The .lngs 6 are inserted iengthwise through the openings 5, end when the roller is in normal position, the lugs 6 take the position indicated in Fig. 1 and prevent the roller from disengaged accidentally from the guides.

The rollers 7 have the studs 8, 8 or projections formed thereon, which are adapted to engage the outer faces of the guides 3 at eoch side ther of when the roller is normal position, as indicated in Fig. 1. i y

A Weenplote 9 is riveted orv otherwise secured the bottom of the housing 2, which piste may tow d necessary. 7

Serial No. 186,833.

Thefiends of the housing are preferahiy .the movement of the plate 11, either to the right or to the left, the rotation oi the roller in either direction is limited by the studs 8,

which move down into the space between the bottom of the guides 3 and the curved Walls 10 o'lthe housing, as indicated in dob ted lines, 1, with the roller engaging the curved Wells 10 of the housing on the side opposite the direction of movement of the roller. The other studs leave the guide and take e position above the top of the guide until he roller returns to normal position. This prevents the further rotation of the roller, and the further movement of the plate 11 is provided for by its sliding along the stationary roller. The roller will return by gravity to normed position.

in case this sliding of the plate 11 on the roiler s flat spot, it is apparent that by thus iimiting the rotation of the roller so that it cannot make at complete or even a half revolution, said flat spot will never come around in position to engage the wearple-te 9 and so interfere with the free rolling f the roiler,

In F 2, I have illustrated a modified form of my invention in which the roller 12 is provided with lugs 13, which are inserted in the openings 14- in the guides 15, end said lugs when 111 normal posit on assume the position indicated in full lines Fig. 2. Thenhutinents 16 and 17 are provided, which are engaged by the lugs 13 accordingly as the roller is moved to the left or right, as clearly indicated in dotted lines, F 1g. 2. These lugs, in the some manner as above, control the amount of movement of the roller and prevent its Ineking a complete revolution or roll ng suiiicientiy in either direction to bring any fist spot formed by the sliding the plate 1]. on the roller down into position to engage the Weenplote and so interfere With the rolling of the roller.

By my invention, therefore, I provide a very simple and eificient form of side-hearing in which there is s free rolling travel for normal condition, and the roller is of a floating type which is free to move, with no chance of its becoming wedged or fixed in position. While I have shown a roller in the drawing, it is apparent that a rocker may be employed, the term roller andlrocker being used to mean the same thing.

By locking the roller in the housing, I am enabled to reduce the height of the housing, for otherwise the walls of the housing would have to be carried up higher in order to prevent the roller from being misplaced. It is apparent that the roller-bearing may be reversed without affecting its operation.

What Ielaim is:

1. A roller bearing for railway cars com prising a ho'using, a single roller in said housing, single faced guides at opposite sides of said housing having upwardly converging guide faces, projections on each end of said roller at opposite sides of said guides, and means for controlling the rolling movement of said roller to less than a complete revolution in either direction.

2. A roller bearing for railway cars coin prising a housing, a single roller in said housing, single faced guides at opposite sides of' said housing having upwardly converging guide faces, projections on each end of said roller at opposite, sides of said guides,

and end portions on said housing with which the roller en ages in either direction to limit the travel 0 said roller to less than a complete revolution.

3. A roller bearing for railway cars comprising a housing,'a single roller within said housing, guides at opposite sides of said housing having upwardly converging guide faces, pro ectlons on each end of said roller at opposite sides of said guides, and curved ends *on said housing, whereby when said roller comes into engagement with one of said ends the projections on that side will seat themselves in the space formed by the juncture of said conical guides with said curved end.

4. A roller bearing forrailway cars comprising a housing, a roller contained within said housing, inclosures formed on the inner sides of said housing, abutments in said inclosures, and projections on said roller located in said inclosures and adapted to engage said abutments as"the roller moves in either direction.

In testimony whereof I, the said VINCENT J. Bunny, have hereunto set In hand.
